What is causing movement in multicellular organism?
Movement in multicellular organisms is typically controlled by muscles, which contract and relax in response to nerve signals. This coordinated activity allows organisms to perform functions such as walking, running, and breathing. Hormones and chemical signals also play a role in regulating movement in response to various stimuli.
What do you call the response to stimuli of makahiya?
The response of the makahiya plant (Mimosa pudica) to stimuli is known as "thigmonasty" or "seismonasty." This phenomenon involves the rapid folding of its leaves and drooping of its stems when touched or disturbed, serving as a defense mechanism against herbivores. This reaction is a form of movement that occurs in response to physical stimuli.
What part of the midbrain is a reflex center that controls movement of the head and eyeballs in response to visual stimuli and the head and trunk in response to auditory stimuli.?
The part of the midbrain that serves as a reflex center for controlling head and eye movements in response to visual stimuli, as well as head and trunk movements in response to auditory stimuli, is called the superior colliculus. It plays a crucial role in coordinating visual and auditory reflexes, helping to orient the head and eyes toward stimuli in the environment.
What are the types of movement in plants in response to stimuli?
Plants exhibit two main types of movement in response to stimuli: tropisms and nastic movements. Tropisms are directional growth responses, such as phototropism (growth towards light) and gravitropism (growth in response to gravity). Nastic movements, on the other hand, are non-directional, such as the opening and closing of flowers or the rapid movement of the Venus flytrap. Both types of movement enable plants to adapt to their environment and optimize their chances for survival.
What are chemo tropism and hydro tropism?
Chemotropism : The movement of plant parts in response to chemical stimulus is called chemotropism. example- formation of pollen tube by pollen grains in order to transfer male gamete to the ovary. Hydrotropism : The movement of plant parts in response to water is called hydrotropism. example- movement of roots in search of water.
What is meant by chemotropism?
Tropism is defined as the movement, generally by a plant, due to outside stimuli; direction of sunlight being a primary stimulus. Chemotropism is defined as oriented growth or movement in response to a chemical stimulus.
Explandiate the following tropic movement chemotropismgalvanotropismand trantotropism?
Chemotropism is the directional growth or movement of an organism in response to chemical stimuli, guiding its movement towards or away from the source. Galvanotropism is the directional growth or movement of an organism in response to electrical stimuli. Thigmotropism is the directional growth or movement of an organism in response to physical touch or contact with a solid surface.
What are Differences between phototactic and chemotactic stimuli?
Phototactic stimuli are related to an organism's response to light, where they move towards or away from light sources. Chemotactic stimuli involve an organism's response to chemical signals in their environment, leading to movement towards or away from the source of the chemical. Both types of stimuli play important roles in an organism's survival and behavior.
The responses of plants to external stimuli are called?
The responses of plants to external stimuli is called Tropism.Here are some tropisms:* Chemotropism, movement or growth in response to chemicals * Geotropism (or gravitropism), movement or growth in response to gravity * Heliotropism, movement or growth in response to sunlight * Hydrotropism, movement or growth in response to water * Phototropism, movement or growth in response to lights or colors of light * Thermotropism, movement or growth in response to temperature.
What is the movement of plant in response to stimuli in the environment?
tropism
What is the information acquired by chemical stimuli or response to the environment that is directed by the brain?
It Is Sensory

What is chemical stimuli?
Chemical stimuli are signals that are produced and detected through chemical processes. In biological systems, chemical stimuli can trigger specific responses in cells or organisms, such as signaling molecules that lead to a physiological response or behavior. Examples include pheromones that attract mates in animals or neurotransmitters that mediate communication between nerve cells.

What is the medical term meaning loss of movement?
Akinesia means loss of movement. Rigor means rigidness preventing response to stimuli - also a loss of movement.
The plant part that facilitates a leaf blade being oriented at right angles to the sun is a?
A pulvinus is the plant part responsible for facilitating a leaf blade's movement to be oriented at right angles to the sun. It is a specialized joint or swelling found at the base of the petiole that allows for controlled leaf movement in response to environmental stimuli such as light intensity. This mechanism helps optimize light interception for photosynthesis.
